EXTENSIBLE JACKET FOR REVOLVERS.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed July 26, 1906. Serial No. 327,878.

To LZZ whom, t may concern:

Be it known that I, Joni:r AnRIANsoN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of-Illinois, have invented certain new and useful Improvements in an Extensible Jacket for Revolvers, of which the following is a clear, full, and exact description.

My invention relates to small fire-arms such as revolvers, pistols and the like, and its object is to provide novel means whereby a greater accuracy in :firing is obtained and the efiiciency of the weapon correspondingly increased, and also to rovide means for deadening the report of t e explosion by the diffusion or breaking of the residual gases at the moment they leave the mouth of the firearm. Heretofore when it has been necessary to accurately use a revolver at a long range, say fifty yards or over, it has generally been supported on some articial means and aimed, or else secured to the side of a riiie or shot-gun by certain devices.

My present invention, however, carries out its object in an entirely dierent manner, by employing suitably constructed telescopic tubes that may automatically lock or be secured concentric with the barrel of the revolver. Vhen in use these tubes are extended to form an elongated jacket and its forward end is adapted to be held in the hand when aiming the weapon, thus giving the average user a more accurate sight than is possible at present when the revolver is supported and aimed by one hand. It will be readily understood that by the use of two supporting points considerable lateral movement, so detrimental to accuracy when firing, will be entirely overcome and avoided. This I accomplish by the means hereinafter fully described and as more particularly pointed out in the claims.

In the drawings Figure 1 is a side elevation of a revolver of any well-known make, showing my improved jacket secured thereto in extended position. Fig. 2 is a top plan view thereof. Fig. 3 is a longitudinal central section of the extensible jacket, drawn to an enlarged scale. Fig. 4 is a detail view of the manner of removably and automatically locking the jacket to the revolver. Fig. 5 is a side elevation of a modified form of my invention, showing the extensible jacket in longitudinal vertical section. Fio. 6 is an elevation of still another modified form, showing the manner of constructing a cane in accordance with my invention. Fig. 7 is a detail View of the same, showing the construction of the upper portion of the shaft of the cane to receive the revolver. Fig. 8 is a transverse section of a modified form of tubln gReferring to the drawings A represents a revolver of any well-known type or make, to which my attachment is adapted to be applied. This attachment comprises two telescopic metal tubes B and C, that may or may not be provided with perforations a, c, as shown, and are, preferably, so arranged that the smaller tube B will engage and iit around the barrel D of the revolver. Cut in the lower portion of the outer tube C is a longitudinally elongated slot c, that extends to within a short distance of each end of the tube, and is adapted to accommodate a small pin secured to and projecting downwardly from the forward end ofr inner tube B, said pin being utilized to limit the length of the sliding movement of the tubes upon each other. The slot cis, preferably, covered with a thin sheet metal plate E, to strengthen the tube and protect the hand of the user from the particles of burnt powder that are usually emitted from the revolver when fired. This plate E is, preferably, provided with a slight longitudinal channel e where it arches over the slot c, to allow the pin b to freely slide therein, while at the forward end of the tube, said channel is slightly increased in depth to provide a suitable nger-grip F, that is, preferably, held in the left hand to steady the barrel when ring the revolver. yA ring G made of steel or other spring metal is secured to the rear end of the outer tube to cause just enough friction to prevent the telescopic tubes from working too freely one on lthe other, and the opposite end of said tube is provided with a sight lug g' arranged in longitudinal alinement with the sight lug on the end of the revolver barrel. These telescopic tubes forming the extensible jacket are secured to the revolver barrel in a novel manner now to be described. Secured to the upper surface of the revolver barrel and extend ing, preferably, a distance from the rear edge of the sight lug to near the stock thereof is an elongated spring catch or plate I-I that is, l

preferably, slightly less in thickness than the tube. This plate is secured at its forwarded end only to the metal barrel by soldering or otherwise, allowing its rear portion free to be moved up and down as desired. Cut in one IOO side edge of this rear portion, which is, preferably, wider than the forward end, is a small notch h', so constructed and arranged that it will engage and interlock with the tube. Extending longitudinally into the upper surface of the inner tube is a tapering slot of a length sufficient to allow the sight to pass freely therein till the rear edge of the tube engages the stock of the revolver, and projecting transversely into said slot from the edge of the tube is a rectangular or other shaped lug i that corresponds to and alines with the notch h in the spring plate H.

In ordinary use the telescopic tubes are disconnected from the revolver and carried in the pocket in a closed position. When it is desired to use the same it is held, preferably, in one hand, and the revolver, being held by the other hand, can be quickly inserted into the rear of the tubes until the catch snaps into place, when the outer tube can be drawn over the inner tube its full length, and the revolver aimed and steadied by the hand gripv F until ready to re.

In the modification shown in Fig. 5 of the drawings, the extensible jacket is firmly secured to the revolver, and comprises aseries of short telescopic tubes J, J, each of which is about the length of the revolver barrel, and may or may not be provided with perforations j, as employed in the preferred form. The first tube is permanently secured to the barrel, and provided with a lug K that slides in a slot 7c in the next surrounding tube, and each of the remaining tubes are provided with slots and lugs in the same manner as the first one. Surroundin the end of the revolver barrel is an annu ar ring or ferrule L, preferably, of a thickness corresponding to the difference between the diameter of the forward and rear ends of said barrel, and is utilized to prevent the lateral play of the telescopic tubes when the same are extended in use.

In Figs. 6 and 7 of the drawings I show my device in connection with a walking cane M, that is, preferably, made of hollow tubing, and, preferably, provided with a series of small perforations m at the upper end thereof, and with a handle or head N, that is secured to said shaft by means of a bayonetslot connection n. Diametrically opposite the bayonet-slot n, the shaft of the cane .is provided with a slot O of the same dimensions and shape as the slot shown in the preferred form, so that, when the cane-handle is removed, the revolver can be immediately inserted therein and aimed in a manner as heretofore described.

extend preferably the length of the tube, per'- mitting the tubes to telescope and slide upon each other in proper manner.

What I claim as new is l. A revolver or similar fire-arm provided with a collapsible jacket.

2. A revolver or similar fire-arm rovided with a telescopically collapsible jac ret.

3. A revolver or similar fire-arm provided with a removable collapsible jacket.

4. The combination with a revolver, of a collapsible jacket consisting of two or more telescopic tubes.

5. The combination with a revolver, of a removable collapsible jacket consisting` of two o r more perforated telescopic tubes.

9. A revolver or similar fire-arm provided with a spring-plate on the barrel thereof, and a removable telescopically collapsible jacket surrounding the same and engaging said spring-plate.

10. The combination with a revolver or similar fire-arm, and a spring-catch secured to the barrel thereof, of an extensible jacket engaging said catch and consisting of a number of telescopic tubes slidably mounted upon each other.

11. The combination with a revolver or similar fire-arm, and a spring-catch secured to the barrel thereof, of an extensible jacket engaging said catch and consisting of a number of telescopic tubes slidably mounted upon each other and provided with a plurality of openings.

12. rlhe combination with a revolver or similar fire-arm, and a spring-catch secured to the barrel thereof, of an extensible jacket engaging said catch and consisting of a number of telescopic tubes slidably mounted upon each other, the innermost of said tubes being provided with a longitudinally elongated slot that engages and locks with said spring-catch.

13. The combination with a revolver or IIL) similar fire-arm, and a spring-catch secured of telescopic tubes the innermost of Whichis providedy With a longitudinally elongated slot, and a transverse lug projecting into the same that engages the cut-out portion in said spring-plate and removably secures said jacket to said revolver.

l5. The combination With a revolver or similar fire-arm7 and a spring-plate on the barrel thereof that has a cut-out portion, of an extensible jacket consisting of a number of perforated telescopic tubes the innermost of which is provided With a longitudinally elongated slot7 and a transverse lug projecting into the same that engages the cut-out portion in said spring-plate, and removably secures said jacket to said revolver.

16. The combination With a revolver or similar 'lire-arm, and a spring-plate in the barrel thereof that has a cut-out portion7 of an extensible jacket consisting of a number of telescopic tubes each having a limited movement upon the tube it surrounds, the innermost of which is provided With a longitudinally elongated slot, and a transverse lug projecting into the same that engages the cut-out portion in said spring-plate and removably secures said jacket to said revolver. In testimony whereof I have hereunto set my hand this 9th day of July, A. D., 1906.
